Why not just turn the temperature up higher? Reduce fan speed? Turn on Eco mode? It sounds like the A/C is working just fine (very good) but the control algorithm is a bit problematic (not great, but not horrible either). There is a temperature sensor somewhere in the center console, so why not try vacuuming everywhere it looks like there is a small hole for temperature sensing, and the problem may go away.
